Hair analysis is increasingly regarded as an effective means for assessing drug and alcohol consumption. Hair traps biomarkers within the fibers of the emerging strand, offering a historical record of substance use. When taken from the scalp, hair can reveal up to a three-month history of drug and alcohol exposure. Collecting hair is straightforward, somewhat tamper-resistant, and easy to transport.
A 1.5-inch segment of around 200 hair strands (approximating the girth of a #2 pencil) nearest the scalp yields about 100mg, the preferred quantity for preliminary and confirmatory testing. For tests like EtG, additional panels, or those exceeding 10 panels, a 150mg sample is advisable. Utilizing a jeweler’s scale for measurement is recommended. If scalp hair isn’t available, a similar quantity of body hair is acceptable. Note that when head hair is mentioned, it refers exclusively to scalp hair, with body hair encompassing all other types (e.g., facial, axillary).
Process Overview
The laboratory analysis of a drug test result incorporates four primary phases: Accessioning, Screening, Extraction, and Confirmation.
During Accessioning, a sample is initially processed into the lab's system. This phase involves checking that the sample was securely sealed and correctly shipped, allocating a random LAN (Laboratory Accessioning Number), and finalizing any requisite data entry not covered by an electronic chain of custody system.
Screening acts as a preliminary assessment to identify substances of abuse. Though cost-efficient for ruling out drug use in most cases, any positive results from Screening require subsequent confirmation for legal validity. Samples that are initially positive in Screening need a secondary verification.
Should the Screening process indicate a potential positive result, additional hair is sourced from the original sample for Extraction. Here, the extraction of drugs from hair occurs at a significantly lower concentration than in other tests (such as urine or oral fluid), rendering hair drug testing one of the most challenging methodologies to conduct.
Verification of positive Screening outcomes is performed using GC/MS, GC/MS/MS, or LC/MS/MS techniques. All samples presumed positive undergo washing prior to confirmation, as necessary. The full laboratory process is scrutinized from Accessioning to Confirmation under the CAP (College of American Pathologists) Hair directive and the ISO / IEC 17025 accreditation standards.
